🔌 Function

The sea water pump impeller rotates inside the raw-water pump body to draw cooling water from outside the vessel and circulate it through the engine's cooling system. A worn, hardened or damaged impeller can reduce water flow and cause overheating, especially at idle, low speed or under load.

Common signs of failure:

• Engine overheating

• Weak or reduced raw-water flow

• Damaged, cracked or missing impeller blades

• Rubber fragments found in the cooling system

• Overheating after start-up or at idle

• Reduced cooling performance under load

• Pump body damage caused by a failed impeller

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
